We have an issue with rich snippets gone from Google SERP, asfter researching a while we've changed reviewCount with ratingCount. Now pages seems to be ok in Google testing tool. However no rich snippets appearing for several weeks.
Any ideas? Please advice.

Rich snippets come and go in the serps. You can even have rich snippets show for a page for certain keywords but not for others. I also find pages rich snippets that are updated often do not really make any difference.
I find breadcrumb rich snippets once discovered seem to stay.
Review rich snippets for the most part seem to stay as well.
Review aggregate and author rich snippets seem to appear and disappear a lot though (like one month there and the next month gone, repeat). These are pages that are usually linked more to (both externally and internally) using different link text so I have wondered if that every plays into it.
